				 Vinokourov, one of the most famous Kazakh athletes, won 
				stages at most major races and the gold medal at the London 
				Olympics but he also served a two-year ban after testing 
				positive for blood doping at the 2007 Tour de France. 
				 
				"Alexander Vinokourov resigned as bid ambassador, he was only 
				part of the application phase," a bid official said in a 
				statement. 
				 
				Almaty bid vice-chairman Andrey Kryukov said recently that 
				Vinokourov would stay on as ambassador after fielding questions 
				during the International Olympic Committee's visit to evaluate 
				the bid regarding his doping offences. 
				 
				Sources said IOC officials had not been happy he was chosen as a 
				bid ambassador given their organization's "zero tolerance" 
				policy on doping and drug cheats. 
				 
				Almaty and Beijing are the only two candidates for the 2022 
				winter Games after four other cities dropped out due to 
				financial concerns and a lack of local support for the project.
